PIETER F. AGENBRAUN, OF STANFORD, CNNECIICUT, ASSIGNOR TO THE YALE & TOWNE MANUFACTURING COMPANY, 0F STANFORD, CONNECTICUT;

SASH-CENTER To all whom it may concern:

Be it known that 1, PETER F. AUGEN- BRAUN, of Stamford, in the county of F airfield and State of Connecticut, have invented certain new and useful lmprovements in Sash-Centers; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in sash centers, the object being to provide a construction which may be readily and easily secured in position to the sash and frame, and by means 'of which a sash or transom may be held in different positions of adjustment.

l/Vith this object in view my invention consists in the parts and combination of parts as will be more fully described and pointed out in the claims.

1n the accompanying drawings, Figure l is a view in elevation of my device, lfig. 2 is a view in elevation showing the two members separated. Fig. 3 is a view in section. Fig. Ll is a perspective view of the friction member removed and Fig. 5 is a view of the latter with its parts disconnected and sepa rated.

1 and 2 represent the two hinge members each of which is provided with an enlarged middle portion having a recess 3 therein, the two recesses being circular in form and of a size suiiicient when assembled to receive the friction member' d. Each hinge member 1 and 2 is also provided with the holes 5 for the attaching screws, and each is also provided centrally with a circular boss 6, one of which has an angular opening through same for the reception of the angular end 7 of pintle 3, While the other has a circular opening for the reception of the cylindrical end 9 of pintle 8a It will therefore be seen that when the two hinge members 1 and 2 are secured respectively to the frame and sash, transom or other like part, the pintle will b-e held rigid or fixed with relation to the hinge member carrying same, while the other hinge member will have a pivotal connection thereon, thus permitting one hinge member to turn on the other and be sustained and supported by such other member.

The hinge member 2 which is loosely mounted on the pintle 8, is provided with one or more recesses l0 communicating with Specification of Letters Patent.

the recessed seat 3 therein, and adapted to receive the ears 11 formed on one member of the frame of the friction member t, so that when the two hinge members are assembled, the pintle S remains fixed with relation to one hinge member and the frame of the friction member 4: remains fixed with relation to the other hinge member. 'lhe pintle is provided with a central enlargement 12 which is noncircular in cross section, and the friction member has a plate provided with a central opening non-cir cular in cross section and conforming in shape and size with the enlargement on the pintle, so that when the parts are assembled, the said plate will be held against independent movement on the pintle of hinge member 1. This friction member l1 is composed of the disk shaped plates 13 and 13a the former of which is provided with the ears 11 which rest in the recesses 10 of the hinge member 2. The two plates 13 and 13 are connected and held apart by the fiat spacing rivets 14;, and each plate is provided intermediate the rivets with elongated holes 15 for the reception of the reduced ends of the hardened steel rollers or pins 15a. These pins or rollers 15a are therefore journaled at their ends in the two plates 13 and 13a, and they are yieldingly forced toward the center of the plates by the helical spring 1G preferably made of round wire, and located between the plates 13 and 13a outside of the pins 15a and also outside the rivets 14, so as to bear against the pins with a yielding pressure and limit the outward .movements of the latter.

Located between the plates 13 and 13a and intermediate the pins 14 is the friction plate 17. This plate, (two in the present instance) is provided with a corrugated periphery which bears against the pins 15a, the latter being normally held in the depressions of the corrugations by the spring 1G. rlhis plate or plates 17 is provided with a non-circular opening 13 conforming in size and shape to the enlargement 12 on pintle 8, so that when the plate 17 is in position on the pintle, it can have no movement independent of the pintle. llt will therefore be seen, that one portion of the friction member to wit; plate 17 .is fixed relatively to hinge member 1, and the plates 13 and 13a and the pins 14 carried thereby, are fixed relatively to the other hinge member 2, so that when one hinge member (the member secured to the sash or transom) ysay'2, is turned, it carries the plates 13 and 13a and the pins 14 with it. As the pins move they ride over the projections on the periphery of the plate 17, and are forced bythe spring into the depressions between the projections, until the point is reached where it is desired to have the sash, transom or center come to a rest.

In the construction shown the projections and depressions, on the plate 17 are so formed, and the pins 15a are so located, that all the pins, (if there be more than one) are simultaneously in engagement with the projections on the plate 17 or are in depressions between said projections.

If therefore the hinge member 1 be secured to the frame, and the member 2 be secured to the sash or transom, the sash or transom can be readily turned by a push or pull, and when the power is withdrawn, the automatic friction devices will hold it in such position whether it be closed or open, against the possibility of accidental movement.

The device is self contained, hence in order to apply it, it is simply necessary to sccure one hinge member within a proper recess in the sash or transom and the other in a recess in the frame, and when so applied it acts not only as the hinge or center on which the sash, transom or other part turns, but operates to lock it against ac cidental movement.

It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention hence I would have it understood that I do not wish to confine myself to the exact construction and arrangement of parts shown and described, but,

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. A device of the character described, comprising a pair of hinge members, one carrying a pivot on which the other or pivoted section is mounted, and a friction member comprising a plate mounted against rotation on said pintle and having projections 0n its periphery and a casing carried by the pivoted hinge member and carrying spring pressed pins which move in contact with the projection on the edge of the plate.

2. In a device of the character described. the combination with two hinge members one having a fixed pintle on which the other or pivoted member is mounted` of a friction member located intermediate the hinge members and comprising a. circular plate corrugated at its edge, a frame secured to the pivoted hinge member, a pin carried by said frame and bearing against the corrugated edge of the circular plate and a spring for yieldingly holding said pin in contact with the edge of the plate.

3. In a device of the character described, the combination with two hinge members one having a pintle on which the other or pivoted member is mounted, of a friction element comprising a frame, a circular plate corrugated at its edge, a plurality of pins engaging the corrugated edge of the plate, and a spring ji'ieldingly holding the pins in contact with the plate, the said corru gated plate being secured to the pintle carried by one hinge member and the frame carrying the pins secured to the other hinge member.

L1. In a device of the character described, the combination with two hinge members each having a recess therein, and a pintle fixed to one of said members, passing through both recesses and through the other member, of a friction member located within said recesses, and comprising a frame secured to one hinge member, a plate secured against rotation on the pintle of the other hinge member, the said plate having a corrugated edge, pins loosely mounted in said frame and a spring embracing the setl of pins and yieldingly holding them in contact with the corrugated edge of the plate.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
